Imagine a simple dietary supplement that could help create a calmer, less violent society. This is the suggestion of a recent study conducted by the University of Pennsylvania, published in Aggressive and Violent Behavior. The research shows that consuming omega-3 fatty acids, well-known for their heart health benefits, could also play a critical role in reducing aggressive behaviors.

30% Reduction in Aggression Across All Groups
The study, which analyzed data from 29 randomized clinical trials, found that omega-3 supplementation led to a 30% reduction in aggressive behaviors, whether verbal, physical, bullying, or violent. This reduction occurred regardless of age, gender, psychological profile, treatment duration, or dosage.

Researchers distinguished two types of aggression: reactive aggression, an impulsive response to a perceived threat, and proactive aggression, which involves planning. Remarkably, omega-3 was effective in reducing both forms, providing a comprehensive approach.

Neurobiological Mechanisms at Play
These findings are attributed to the impact of omega-3 on the brain. Omega-3 fatty acids play a crucial role in the structure and function of neurons. They regulate neurotransmitters, gene expression, and reduce brain inflammation, all factors associated with aggression.

Toward a Broader Use of Omega-3 to Reduce Violence?
Given these promising results, researchers advocate for the widespread use of omega-3 supplements in violence prevention programs in schools, healthcare settings, and even the judicial system. Dr. Adrian Raine, a neurocriminologist and the study’s lead author, asserts: “Omega-3 could be an innovative and affordable solution to address violence in society.”

Although omega-3 is not a magic bullet, its safety, availability, and low cost make it a potentially valuable tool to complement existing psychological and psychiatric treatments for aggression.

Omega-3: A Valuable Supplement for Children
Researchers emphasize that integrating omega-3 into children’s diets could positively impact their behavior. A few servings of fatty fish each week might contribute to more harmonious interactions at home and school.

Future research will need to explore the long-term effects of omega-3 supplementation and examine other aspects like genetics or brain imaging. However, it is already clear that omega-3 could play a key role in fostering a more peaceful society.
